Garmin echomap chirp 40 series Owner's Manual

Cleaning the Screen

Cleaners containing ammonia will harm the anti-reflective

coating.

The device is coated with a special anti-reflective coating which

is very sensitive to skin oils, waxes, and abrasive cleaners.

Apply an eyeglass lens cleaner specified as safe for anti-

reflective coatings to the cloth.

Gently wipe the screen with a soft, clean, lint-free cloth.

Screenshots

You can capture a screenshot of any screen shown on your

chartplotter as a bitmap (.bmp) file. You can transfer the

screenshot to your computer.

Capturing Screenshots

Insert a memory card into the card slot.

Select Settings > System > Display > Screenshot Capture

> On.

Go to a screen you want to capture.

Hold HOME for at least six seconds.

Copying Screenshots to a Computer

Remove the memory card from the chartplotter, and insert it

into a card reader that is attached to a computer.

From Windows

Explorer, open the Garmin\scrn folder on the

memory card.

Copy a .bmp file from the card and paste it to any location on

the computer.

Troubleshooting

My device will not acquire GPS signals

If the device is not acquiring satellite signals, there could be a

few causes. If the device has moved a large distance since the

last time it has acquired satellites or has been turned off for

longer than a few weeks or months, the device may not be able

to acquire the satellites correctly.

• Ensure the device is using the latest software. If not, update

the device software

(Updating the Device Software, page

• If the device is using an internal GPS antenna, make sure the

device has a clear view of the sky so the internal antenna can

receive the GPS signal. If it is mounted inside of a cabin, it

should be close to a window so it can receive the GPS signal.

If the device is mounted inside a cabin and cannot be placed

in a location where the device can acquire satellites, use an

external GPS antenna.

My device will not turn on or keeps turning off

Devices erratically turning off or not turning on could indicate an

issue with the power supplied to the device. Check these items

to attempt to troubleshoot the cause of the power issue.

• Make sure the power source is generating power.

You can check this several ways. For example, you can

check whether other devices powered by the source are

functioning.

• Check the fuse in the power cable.

The fuse should be located in a holder that is part of the red

wire of the power cable. Check that the proper size fuse is

installed. Refer to the label on the cable or the installation

instructions for the exact fuse size needed. Check the fuse to

make sure there is still a connection inside of the fuse. You

can test the fuse using a multimeter. If the fuse is good, the

multimeter reads 0 ohm.

Appendix

NOTICE

• Check to make sure the device is receiving is at least 10 V,

but 12 V is recommended.

To check the voltage, measure the female power and ground

sockets of the power cable for DC voltage. If the voltage is

less than 10 V, the device will not turn on.

• If the device is receiving enough power but does not turn on,

contact Garmin product support at www.garmin.com/support.

My device is not creating waypoints in the correct

location

You can manually enter a waypoint location to transfer and

share data from one device to the next. If you have manually

entered a waypoint using coordinates, and the location of the

point does not appear where the point should be, the map

datum and position format of the device may not match the map

datum and position format originally used to mark the waypoint.

Position format is the way in which the GPS receiver's position

appears on the screen. Commonly displayed as latitude/

longitude in degrees and minutes, with options for degrees,

minutes and second, degrees only, or one of several grid

formats.

Map datum is a math model which depicts a part of the surface

of the earth. Latitude and longitude lines on a paper map are

referenced to a specific map datum.

Find out which map datum and position format was used

when the original waypoint was created.

If the original waypoint was taken from a map, there should

be a legend on the map that lists the map datum and position

format used to create that map. Most often this is found near

the map key.

On the chartplotter, select Settings > Units.

Select the correct map datum and position format settings.

Create the waypoint again.
